Image Processing Apparatus, Image Processing Method, Program, and Recording Medium - An image processing apparatus includes a detector, a setting unit, and an image generator. The detector detects a target object image region from a first image. When one or more predetermined parameters are applicable to a target object within the region detected by the detector, the setting unit sets the relevant target object image region as a first region. The image generator then generates a second image by applying predetermined processing to either the image portion within the first region, or to the image portions in a second region containing image portions within the first image that are not contained in the first region.

Learning Apparatus and Method, Recognition Apparatus and Method, Program, and Recording Medium - A learning apparatus includes an image generator, a feature point extractor, a feature value calculator, and a classifier generator. The image generator generates, from an input image, images having differing scale coefficients. The feature point extractor extracts feature points from each image generated by the image generator. The feature value calculator calculates feature values for the feature points by filtering the feature points using a predetermined filter. The classifier generator generates one or more classifiers for detecting a predetermined target object from an image by means of statistical learning using the feature values.

INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD AND COMPUTER PROGRAM PRODUCT - An information processing apparatus, information processing method and computer program product cooperate in detecting a first target object contained in image information. Image information of an image is received through an interface. A processing circuit determines whether a first target object in the image information has not yet been detected. A determination is also made regarding whether a second target object in the image information has been detected. An image quality parameter of the image is modified to assist subsequent detection attempts in recognizing the first target object when the first target object has not yet been detected but the second target object has been detected.
